        * config/rs6000/rs6000.md (movdi_mfpgpr): Remove POWER mnemonic.
        (movdi_internal64): Same.

        * config/rs6000/rs6000.md (save_gpregs_<mode>): Replaced pattern
        with a set of similar patterns, where the MATCH_OPERAND for the
        function argument is replaced with individual references to hardware
        registers.
        (save_fpregs_<mode>): Ditto
        (restore_gpregs_<mode>): Ditto
        (return_and_restore_gpregs_<mode>): Ditto
        (return_and_restore_fpregs_<mode>): Ditto
        (return_and_restore_fpregs_aix_<mode>): Ditto
